Pregnant? Tmi

My SO and I aren't ttc but we decided if it happens it happens. Last month we had sex multiple times and then he had to leave for a little over a month for work. He came back on the 26th and there has been a lot of sex since then. But I haven't had my period. Just a very light 24 hr kinda period in mid August... I'm 2 weeks late but clear blue pregnancy test came back negative twice
